Abstract
L'invention concerne un procédé de préparation de carbonate de calcium, dans lequel l'étape de caustification permet de préparer un carbonate de calcium bon marché, fusiforme ou en forme de grain de riz, ce carbonate de calcium pouvant, comme charge de pâte à papier, conférer les propriétés adéquates au papier, telles que la blancheur, l'opacité et la capacité de prévention d'usure de la toile. Lorsqu'on utilise une liqueur blanche pour l'extinction de la chaux vive, la première étape d'extinction de la chaux s'effectue de telle sorte que la chaux vive utilisée possède une teneur en carbonate de calcium inférieure à 10 % en poids, et l'extinction de la chaux s'effectue dans une concentration de 0,5 à 60 %, une liqueur blanche étant utilisée pour préparer un lait de chaux. Par ailleurs, lorsqu'on utilise une liqueur verte pour l'extinction de la chaux vive, la première étape d'extinction de la chaux s'effectue de telle sorte que la teneur en carbonate de calcium de la chaux vive utilisée est comprise entre 0,1 et 10 % en poids et l'extinction de la chaux s'effectue dans une concentration de 20 à 60 %, une liqueur verte étant utilisée pour préparer un lait de chaux. Une réaction de caustification dans la deuxième étape est menée dans des conditions de vitesse d'addition de liqueur verte comprise entre 0,02 et 0,5 cc (liqueur verte)/min/g (chaux vive), et à une température de réaction comprise entre 20 et 105 DEG C pour préparer un carbonate de calcium fusiforme ou en forme de grain de riz.
